Lesson 4 Summary

Lesson 4, page 14 of 14

Congratulations on creating your first GoldSim model! You've built an entire GoldSim model from scratch, and along the way, have learned to

• Create a new model and define the simulation settings;
• Add a Reservoir A Stock element that integrates and conserves flows of materials. element and define its properties;
• Add an Expression element A Function element that produces a single output by calculating user-specified mathematical expressions. and create a feedback loop;
• Add a Stochastic An Input element that allows you to quantitatively represent the uncertainty in a model input by defining it as a probability distribution. element to define an uncertain variable, and define a trigger to resample it;
• Add a Timed Event An element that generates discrete signals based on a specified rate of occurrence. element to represent random events;
• Add a Discrete Change element An element that generates discrete change signals that can subsequently modify stock elements. to represent the consequence of a discrete event;
• Add an Extrema element A Function element that records the highest (or lowest) value of a variable observed during a simulation. to track the lowest (or highest) observed value for an output; and
• Add Time History Result A chart or table showing how a model variable changes with time. and Distribution Result A chart showing the uncertainty in the output of a probabilistic simulation. Distribution results can take the form of a Cumulative Distribution Function, a Complementary Cumulative Distribution Function, or a Probability Density Function.elements The basic building blocks with which a GoldSim model is constructed. Each element represents a feature, pararamer, process or event in the model..

We covered most of this material quickly and did not dive into too many details.However, hopefully this simple example provided you with both a basic understanding of how GoldSim models are built, along with an indication of the power of GoldSim.

Next we will provide a quick overview of some of GoldSim's advanced features, and will conclude the Tutorial by discussing how you can learn more about software's features and capabilities and work toward becoming an expert GoldSim modeler.
